The study will be carried out in 50 subjects aged 21-65 years, with alcohol dependence as their primary complaint, and without other serious medical or psychiatric conditions. An additional inclusion criterion will be the presence or history of significant anxiety symptoms on self report. Subjects will be admitted to the NIAAA research inpatient unit at the NIH Clinical Center through a platform training and natural history protocol which provides basic assessments and standard withdrawal treatment if needed. Patients will enter into the present protocol once such treatment, if needed, is completed. The present protocol will be started with a 1 week single blind placebo lead-in. During this phase, a baseline alcohol cue-reactivity session will be carried out according to established procedures, and urges to drink will be assessed. Cue-responsive subjects only, appr. 70% of alcohol dependent inpatients, will be randomized to active treatment or placebo, and enter the active treatment phase. The active treatment arm will receive 50 mg once daily of LY686017by oral intake, while the placebo group will continue to receive placebo in a double-blind fashion. The duration of active treatment will be 3 weeks.
